Not sure why everyone thinks I am joking

“You stop thinking about iterative or recursive. You just say there’s this aggregate. There’s this list and I transform every item in this list. I stop thinking about the particular control structure and order.

That’s very very important idea. I guess it really comes from APL. It’s sort of the really important idea from APL that you stop thinking about control structures and you start thinking about operations on aggregates.”
